KDA 2.1-100-3-DP0-U1-115

The Bosch Rexroth Indramat KDA 2.1-100-3-DP0-U1-115 drive controller from the KDA Spindle Drives series sets a new benchmark for high-performance spindle control with a current rated of 100 A and a continuous current of 70 A output capacity. Engineered for reliable integration, it operates on a rated voltage of 300 V DC bus and supports an attached blower supply of AC 50 Hz or AC 60 Hz to ensure consistent thermal management. The compact module delivers precise current regulation and features advanced diagnostics to monitor power delivery and fault conditions in real time. Its robust design and standardized interface simplify mounting and replacement in demanding manufacturing environments.

Featuring sophisticated power electronics, the controller maintains tight current loops across its current rated and continuous current ranges to optimize spindle acceleration and deceleration profiles. The dual-voltage blower connection (AC 50 Hz, AC 60 Hz) enables flexible cooling options that extend service intervals and enhance long-term reliability under sustained load. High-resolution sensing elements continuously track bus voltage at 300 V and drive current levels, providing accurate feedback for closed-loop speed and torque control. Built-in fault detection safeguards against overcurrent, overtemperature, and bus undervoltage, while configurable thresholds allow seamless integration with higher-level automation systems.

Designed for ease of installation, the KDA 2.1-100-3-DP0-U1-115 drive controller shares mechanical and electrical form factors with other Bosch Rexroth Indramat KDA Spindle Drives, minimizing downtime during retrofits. The unit’s digital interface supports rapid parameter loading and live status monitoring, reducing commissioning time. Backed by Bosch Rexroth Indramat’s global support network, this drive controller offers exceptional performance for high-speed spindles in industries such as aerospace, automotive, and precision machining.
